X-Ray Lumbar Spine
in Ahmedabad –
AP View & Lateral View
Digital X-Ray Lumbar Spine for lower back pain, spondylosis, disc height loss, spondylolisthesis, scoliosis & pre-surgical planning. AP and Lateral views — MD Radiologist reports in same day. 15+ branches open 24/7.
Four Lumbar Spine X-Ray Views Available
Each view reveals different aspects of the lumbar spine. Your orthopaedic surgeon, neurosurgeon, or physician will specify the view required — click a card to understand what it shows and when it is prescribed.
AP View (Antero-Posterior)
Lateral View (Side Profile)
AP + Lateral (Both Views)
Flexion-Extension Views
The AP (Antero-Posterior) lumbar spine X-ray is taken with the patient lying on their back — the beam passes from front to back, producing a frontal view of the five lumbar vertebrae (L1–L5), the disc spaces, the transverse and spinous processes, the pedicles, the sacrum, and the sacroiliac joints. It is the primary view for scoliosis assessment, vertebral body morphology, pedicle integrity (metastases destroy pedicles first — "winking owl sign"), and overall lumbar alignment. It also allows Cobb angle measurement for scoliosis and assessment of transitional vertebrae (sacralization or lumbarization).
- ✅Scoliosis assessment: Lateral curvature of the lumbar spine — Cobb angle measurement on AP view is the standard for scoliosis grading
- ✅Vertebral body morphology: Shape, height, alignment, and density — compression fractures, metastases, haemangiomas visible on AP
- ✅Pedicle assessment: "Winking owl sign" — absent pedicle shadow on AP indicating metastatic destruction; bilaterally present pedicles = no metastasis
- ✅Transitional vertebrae: Sacralization of L5 (fused to sacrum) or lumbarization of S1 — counted on AP view, affects surgical level planning
- ✅Sacroiliac joints: SI joint widening or sclerosis — ankylosing spondylitis, sacroiliitis, and SI joint fractures visible on AP lumbar view
The lateral lumbar X-ray is taken with the patient lying on their side — providing a perfect side-on profile of all five lumbar vertebrae, intervertebral discs, facet joints, spinal canal diameter, and the lumbosacral angle. It is indispensable for measuring disc height loss (the hallmark of degenerative disc disease), detecting spondylolisthesis (forward slipping of one vertebra over another — graded on lateral view), assessing the degree of lumbar lordosis, and identifying posterior element injuries missed on AP view. The lateral view is particularly critical before any lumbar surgery — it defines the operative anatomy precisely.
- ✅Disc height measurement: L1/2, L2/3, L3/4, L4/5, L5/S1 disc heights — narrowing indicates degeneration, the most common cause of chronic low back pain
- ✅Spondylolisthesis grading: Forward translation of one vertebra — Meyerding Grade I to IV graded on lateral view. Most common at L4/5 and L5/S1
- ✅Lumbar lordosis assessment: The normal forward curve — loss of lordosis (military posture, muscle spasm) and hyperlordosis both detected on lateral view
- ✅Posterior element fractures: Spinous process fractures ("clay shoveller"), posterior element compression — invisible on AP view
- ✅Spinal canal diameter: AP canal diameter on lateral view — congenital narrow canal (spinal stenosis) identified before MRI, guides urgency of further imaging
The combined AP + Lateral lumbar spine study provides two complementary projections that together give a complete assessment of the lumbar vertebral column. The AP shows alignment, scoliosis, vertebral body morphology, and posterior element integrity. The lateral adds disc height, lordosis, listhesis, and sagittal canal dimensions. Together they constitute the minimum standard pre-operative lumbar study before any spinal surgery — accepted by all neurosurgeons and orthopaedic spine surgeons. Most radiologists and spine surgeons will not interpret AP alone without the lateral, as significant pathology (spondylolisthesis, disc collapse) is only visible on the lateral view.
- ✅Complete pre-operative assessment: AP provides vertebral level counting and alignment; lateral gives disc heights and listhesis — both essential before lumbar surgery
- ✅Full degenerative disease staging: AP shows lateral osteophytes; lateral shows anterior osteophytes, disc height, and endplate sclerosis — together enable complete spondylosis grading
- ✅Trauma evaluation: AP identifies fracture level and lateral displacement; lateral confirms anterior or posterior element involvement — both required before spine stabilisation
- ✅Best value: Combined AP + Lateral from ₹350 — one joint report covering all findings, cheaper and faster than two separate bookings
Flexion-Extension X-rays are specialised lateral views taken in two positions — maximum forward bending (flexion) and maximum backward extension. These dynamic views detect abnormal motion between vertebrae that is not visible on the standard neutral lateral view. This is the key investigation for spinal instability — identifying vertebral segments that slip excessively during movement, indicating failure of the disc, facet joints, and posterior ligaments as a functional unit. Essential before any spinal fusion surgery — the surgeon needs to know which levels are unstable to determine how many levels to fuse.
- ✅Dynamic spondylolisthesis: Listhesis that increases in flexion and reduces in extension — indicates genuine instability requiring fusion rather than decompression alone
- ✅Post-fusion assessment: Confirms successful fusion by absence of motion between fused levels — standard follow-up at 6–12 months after TLIF/PLIF/ALIF surgery
- ✅Adjacent segment disease: After lumbar fusion, the levels above/below can become unstable — flexion-extension detects this before symptoms worsen
- ✅Pseudarthrosis detection: If motion is detected between levels supposed to be fused — indicates non-union requiring revision surgery
- ✅Pre-dynamic stabilisation: Before insertion of dynamic stabilisation implants, the degree of mobility at target levels is quantified to select the appropriate implant size

What is an X-Ray Lumbar Spine?
A rapid, low-cost investigation using controlled X-ray beams to produce detailed images of the five lumbar vertebrae, intervertebral discs (indirectly), facet joints, and the spinal canal — the lower back's bony architecture in full detail.
What Lumbar Spine X-Ray Shows
A lumbar spine X-ray evaluates all five lumbar vertebral bodies (L1–L5), intervertebral disc spaces (height reduction = disc degeneration), the sacrum and lumbosacral junction (L5/S1), transverse and spinous processes, pedicles, facet joints, and the sacroiliac joints. Key measurements include disc heights at each level, vertebral alignment, Cobb angle for scoliosis, and the degree of any spondylolisthesis. The bony canal diameter is also estimated on lateral view.
Digital X-Ray vs Film X-Ray
Our Digital Radiography (DDR) lumbar spine systems provide sharper images with 40–60% less radiation than older film or computed radiography (CR) systems. Digital images are instantly available on a diagnostic-quality monitor — adjustable contrast separates bone detail from disc space clarity. Results are delivered digitally in same day with no film processing. Permanent digital archiving allows easy comparison with previous studies.
X-Ray vs MRI for Lumbar Spine
X-Ray Lumbar Spine shows bones, disc space heights, alignment, and calcification excellently. MRI Lumbar Spine shows the actual disc material, nerve root compression, spinal cord signal, and soft tissue detail that X-ray cannot. Standard practice: X-Ray first to assess degeneration severity, alignment, and rule out fractures → MRI if nerve root compression or surgical planning is needed. Most spine surgeons review both X-ray and MRI before surgery. X-ray is also the only view for dynamic instability assessment (flexion-extension).
Radiation Safety
A lumbar spine X-ray involves approximately 0.7–1.5 mSv — slightly higher than extremity X-rays due to the large anatomical area and denser tissue. Equivalent to 3–6 months of natural background radiation. The gonads are adjacent to the lumbar spine beam — lead shielding of the testes in males is standard practice. For females, the ovaries cannot be fully shielded without obscuring the image — non-emergency studies in women of reproductive age are ideally scheduled in the first 10 days of the cycle.
Every Lumbar Structure X-Ray Reads
Systematic evaluation of every bony and joint structure in the lower back — as assessed by our MD Radiologists on every study.
Vertebral Bodies (L1–L5)
The weight-bearing blocks of the lumbar spine — evaluated for shape, height, and density.
- Compression fractures (height loss, wedging)
- Metastases (lytic / sclerotic lesions)
- Vertebral haemangioma (corduroy pattern)
- Schmorl's node (disc herniation into body)
- Paget's disease (picture frame vertebra)
- Osteoporotic vertebral collapse
Intervertebral Discs
The disc spaces between vertebrae — height reflects cartilage integrity (indirect sign).
- Disc height loss at each level (L1–S1)
- Disc space narrowing — spondylosis
- Disc calcification (CPPD / ankylosing)
- Vacuum disc phenomenon (gas in disc)
- Endplate sclerosis (reactive bone)
- L5/S1 disc — most critical level
Posterior Elements & Facets
Pedicles, laminae, facet joints — surgical landmarks for decompression and fusion.
- Facet joint arthropathy (spondylarthrosis)
- Pars interarticularis defect (spondylolysis)
- Spinous process fractures
- Pedicle size & screw trajectory planning
- Posterior hardware assessment post-op
- Laminar fractures in trauma
Alignment & Curvature
The sagittal and coronal balance — critical for surgical planning and scoliosis monitoring.
- Cobb angle — scoliosis measurement (AP)
- Lumbar lordosis angle (lateral)
- Sagittal balance / plumb line
- Spondylolisthesis — Meyerding I–IV
- Retrolisthesis (backward slip)
- Coronal & sagittal imbalance
Sacrum & Sacroiliac Joints
The base of the lumbar spine — the lumbosacral junction is the most commonly symptomatic spinal level.
- L5/S1 disc space height
- Transitional vertebra (sacralization / lumbarization)
- Sacroiliac joint sclerosis (ankylosing spondylitis)
- SI joint widening (trauma, infection)
- Sacral fractures (Denis zones)
- Lumbosacral angle measurement
Post-Surgical Hardware
X-Ray is the primary follow-up tool after lumbar surgery — hardware visible on X-ray at every clinic visit.
- Pedicle screw position & angulation
- Rod placement & connectivity
- Cage position (TLIF / PLIF / ALIF)
- Fusion mass development (lateral view)
- Hardware loosening or breakage
- Adjacent segment degeneration
Common Lumbar Spine X-Ray Findings
Your radiologist evaluates all these features systematically on every lumbar spine X-ray report at Usmanpura Imaging Centre.
Osteophytes
Bony spurs at vertebral endplate margins — the most visible sign of spondylosis. "Lipping" on AP and anterior spurs on lateral view.
Disc Space Narrowing
Reduced height between vertebral endplates — the hallmark of disc degeneration (spondylosis). Graded at each level L1–S1.
Spondylolisthesis
Forward slipping of one vertebra — best seen on lateral X-ray. Meyerding Grade I–V. Most common at L4/5 and L5/S1.
Scoliosis
Lateral curvature of the spine — Cobb angle measured on AP view. <10°: normal; 10–20°: mild; >40°: surgical consideration.
Compression Fracture
Wedge-shaped vertebral body with anterior height loss — osteoporotic or traumatic. Requires differentiation from malignant collapse.
Pedicle Destruction
"Winking owl sign" — absent pedicle shadow on AP view indicates metastatic bone destruction. Urgent oncology referral required.
Pars Defect (Spondylolysis)
"Scotty dog collar sign" on oblique view — fracture through pars interarticularis. Most common in athletes and young patients with back pain.
Loss of Lumbar Lordosis
Straightening of normal lumbar curve on lateral view — indicates muscle spasm, acute disc herniation, or psychological guarding.
Endplate Sclerosis
Increased bone density at endplates adjacent to degenerated disc — Modic Type 1 and 2 changes. Indicates chronic disc disease.
Facet Arthropathy
Narrowing, sclerosis, and osteophytes at facet (zygapophyseal) joints — commonly contributing to lower back pain in adults over 50.
Vacuum Disc Phenomenon
Gas (nitrogen) within a degenerated disc space — appears dark on X-ray. Pathognomonic sign of severe disc degeneration (Kirkaldy-Willis Grade).
Hardware Assessment
Pedicle screws, rods, and cages after fusion surgery — serial X-ray assesses position, loosening, and fusion mass development at each follow-up.

When Should You Get an X-Ray Lumbar Spine?
Your orthopaedic surgeon, neurosurgeon, spine specialist, or general physician may recommend an X-Ray Lumbar Spine for any of the following.
How to Prepare for X-Ray Lumbar Spine
X-Ray Lumbar Spine requires almost zero preparation. Follow these quick guidelines for the best results.
Do's – Before Your Lumbar Spine X-Ray
- ✓Walk in at any time — no appointment or fasting required for lumbar spine X-ray
- ✓Bring your doctor's prescription and any previous X-rays, CT scans, or MRI reports for comparison
- ✓Inform staff of any spinal implants — pedicle screws, rods, cages, or interbody devices (CT is safe with all hardware)
- ✓Tell us if you are pregnant or may be pregnant — the lumbar spine is adjacent to the reproductive organs
- ✓Wear loose, comfortable clothing — or change into a gown; remove belts, metal buckles, and metal jewellery in the lower back region
- ✓For standing scoliosis study: wear stable footwear and stand with equal weight on both feet
- ✓For flexion-extension: warm up gently before arriving — cold muscles limit your range of motion and reduce the diagnostic value of the dynamic views
- ✓Bring a support person if you are in severe pain — positioning may require some movement
Don'ts – What to Avoid
- ✗Do NOT wear jeans with metal rivets, belts with large buckles, or clothing with metal on the lower back
- ✗Avoid wearing lumbar support belts or corsets unless staff instructs otherwise — may need to be removed for X-ray
- ✗Do not apply hot or cold packs with metallic components to the lumbar region just before the scan
- ✗Do NOT move during the 1-second X-ray exposure — even slight movement blurs vertebral endplates and disc space detail
- ✗For females of reproductive age: non-emergency lumbar X-ray is ideally scheduled in the first 10 days of the menstrual cycle — discuss with staff
- ✗Do not attempt flexion-extension views if you have acute unstable fracture — only after orthopaedic clearance
- ✗Avoid requesting unnecessary repeat X-rays — show previous films first; a comparison may be more useful than a new study
- ✗Do not delay emergency lumbar X-ray after trauma — spinal cord compression from unstable fractures worsens with delay
